Flywheel effect of the heavy spiral drum on shearer

LIU Chunsheng1,YU Xinwei1,Yan Xiaolin2(1.College of Mechanical Engineering,Heilongjiang Institute of Science and Technology,Harbin 150027,China;2.Jixi Coal Machinery Limited Company,Jixi 158100,China)  
Based on the load characteristics of shearer cutting drum,the extraordinary function of heavy cutting drum,i.e.wear resistant capacity is pointed out,which could raise cutting drum life and capacity of cutting hard coal.And the application mechanism of flywheel effect is revealed on operating mechanism.According to the conversion model of kinetic energy and potential energy,the concepts of additional inertial torque and additional dynamic cutting intensity are put forward and the relationship between the fluctuation quantity and the moment of inertia of cutting drum is established It provides the necessary theoretical basis for decreasing the shearer vibration and designing reasonable structure of cutting drum.
